So today I was sieging a broken lords city as the necrophages with the starting hero and 3 foragers, on that turn they did nothing and so I moved a Proliferator onto my units army taking the last slot when I did this the enemy then decided to make a army with a stalwart that was garrisoned and attacked my army. I then tried to manual attack of which it went to the fight screen but I couldn't interact with the troops nor could I start the fight. When I came out of the fight and clicked back in it took me back to the fight with the same problem but It also brought up a pop-up saying I was waiting on them. I then reloaded and tried the exact same again and it happened again. after I reloaded again I tried auto fighting it and it worked.

sorry I didn't get and photos or anything and i'm past the point where I can get an auto save back. sorry about that just thought you'd like to know anyway.

It's a known bug. Regularly the combat works normal after reloading save game. I save manually while combat is frozen.

Ah okay then. Thanks!
